Verifying age and other restrictions for selling beer or alcohol

I have a client who wants a website for a Beer Delivery service in Michigan, USA.

For the ECommerce options - is there a way to verify age before purchase? And/or restrict products by age?

Other examples of Beer, wine, or alcohol shipping websites would be appreciated as well.

Thanks!

Hi,

From my research you can't age verify pop-up individual products before purchase. Only the entire website. 

Although, in theory, you should be able to create a page pop up that asks "Are you of legal Drinking Age", everytime someone clicks to view a product's page.

Also, you can add a text warning next to the purchase button of the age restricted products.

Don't forget to create your client's Terms & Conditions , especially with legal issues covered from your State or Province - this would protect them from liability of someone lying about their age to purchase an age restricted item from their website.
